(oi. ssd-20G) k lfClaim.

My invention relates to improvements f in a pressure dyeing machine for yarns, ribbons and other materials.. It; relates more particularly-to piece, ribbon-,skinand rhank dyeing. In the past vsuch dyeing 4lfiasbeen donefby sprayirigY or by soaking in Yan open tank. My process-is done by force pressure against the piece, ribbon, skein or hankinan venclosed tank. Byforcing the liquid` against the material tobe dyed a thorough penetration is; accomplished.- By thefpresenti-method when dyeing ribbons or piece goods the'cons'tru'ction and method is such that it is very difficult to secure-the properI penetration in the old or soaking method.- This is due to the twistin the filling and Warps particularly in synthetic fabrics-and if returnedto `the Avat for additional spraying or soaking thev ribbons or`A piece geodsfinvariably are not penetrated through-and the inside is not the same as the outs-ide, i. e., it has a different shade. In an open tank the dyes have a tendency to oXidiZe and it is also very difficult to maintain uniform temperature. By vat spraying or soaking as is the present method a greater quantity of liquid and dye stuff is used than should be necessary in the dyeing process, and Without eiective results.

A first object accomplished by my said invention is that it affords complete penetration of the dyes into the ribbon, piece goods, hank or skein. A second object is that said penetration is accomplished in shorter time than the partial penetration now effected by the present methods aforestated. If penetration takes too long extra handling causes shifting or chaiing which often makes rejects. A third object is that the dye bath is kept in continual circulation. A fourth object is that the dyes do not oXidize as readily but keep the same consistency which is not so in the present method. A fifth object is a more uniform and even and thorough dyeing throughout the ribbon, piece, skein or hank. A sixth object of my invention is labor saving as the penetration is rapid and thorough. A seventh object of my invention is to get a more concentrated bath which means saving of Water, steam and dyestulfs. An eighth object of my invention is that it improves the Winding, i. e., makes perfect Winding in that the lacing of the skein is not disturbed.

With the present method one can open up the hank or untwist the filling in the pieces and see that the dye has not penetrated and if put back in the vat for further penetration upon a further eX- amination it will disclose a different shade, as the dyes keep oxidizing under the present method,

Yfrom the. end side.

which is not so with my invention, as a result of the oxidation it is necessary to add dyestuifs which are `very, costly in many dark dyes that extra costs are eliminated by my invention. By thus eliminating the extra handling of the material and the time involved in` adding additional dyestuifs there is a definite saving of labor.

By the application of my invention, when using formula dyeing, colors can be added to the stor= age tank Without interruption of the pieces, ribbons, hanks, or skeins,.which operation cannot be accomplished by the present method, Without stopping the dyeing operation and removing the said pieces, ribbons, hanks or skeins.

One formof my invention is illustrated in the accompanying drawings inwhich Figure 1 shows a front elevation View partially in cross section. Figure2 is an end elevation looking at the device Figure 3 is a section on line 3-3'of`l1igure 1. Reading on Figures l and 2 of my drawings they consist of framework IU, a shaft I2, having bearings IIA and perforations I3 and end discs I 4 and I5. Said discs I4 and I5 have a hub portion 31 carrying rod 36 which is free to rotate therein, said rod 36 carries fin member 38 and weight 39. Tank I6 has cover I 1, hinges I8, handle I9, pressure gauge 20, and rests on standards 35. Tube 22 has packing glands 23 Where it connects With shaft I2 and shaft I2 has a packing gland 2l Where it connects with tank I6. Tube 22 leads to pump 24, which is driven by motor 25. Tank I6 has an outlet valve 26 leading to tank 21. Tank 21 has a drain 28 and pipe 29 which connects to pump 24. Shaft I2 carries sprocket 3D, which is connected by chain 3| to a sprocket 32 which is fastened to speed reducer 33 the latter being driven by motor 34. Tank 21 is also supported by brackets 35 which support tank I6 as aforestated.

In operation motor 25 pumps liquid from tank 21 through pipe 29 by means of pump 24 into conduit 22 and hollow shaft I2 and the liquid sprays through perforation I3 over the goods or material to be dyed and fills up tank I6 completely, said liquid is pumped in under pressure, and this pressure is retained in said tank I 6. Shaft I2 may be rotated by motor 34 and regulated by speed reducer 33 as the occasion warrants. Rod 35 revolving with hub 31 of discs I4 and I5 holds and turns the material Within the dyeing liquid and the spraying of the material While the tank is being filled. Rod 36 being free to rotate in hub portion 31 of discs I4 and I5 carries n member 38, and a Weight 39, to prevent the entanglement of the goods during the rotation of shaft I2, as it maintains iin 38 and weight 39 in vertical position during rotation. The retention of said pressure within tank I6 forces the liquid through the goods, thus giving a complete and thorough saturation of dye to the goods. When the pressure becomes too great the relief valve 26 automatically discharges the surplus dyeing liquid into storage tank 21 for the purpose of re-circulation. Said valve may be worked either automatically or by hand. An electric timer may be attached to rod 36 so that as many revolutions may be had as desired.

My invention therefore provides a new and useful means for skein, hank, ribbon, or similar kinds of dyeing by using a pressure machine and method and thus effecting a thorough and not a partial dyeing of said skein, or hank, and the like and likewise effecting a complete dyeing of all of the skein or hank, and the like with the same shade and not having a varying shade, and also using and re-using the same liquid indefinitely without losing the effect of the solution by oxidation, as oxidation would be reduced to a minimum and preventing the changing of the composition of the solution remaining in the vat and thus overcoming theeiect created by using the present machines and methods, i. e., the changing of the composition in the open vat by oxidation.

Experiments and preliminary tests have shown that the dyeing machine and method herein described shows a marked improvement in the speed, quality, labor, liquid, and dyestuf saving, as well as an improvement in the true coloring of the materials dyed, and also the saving of water, and steam, over machines and methods now in use. The present machines and methods are purely machines and methods employing a soaking process, where my device and method is by use of the machine which effects a pressure system and the method is a pressure method of dyeing.

The materials used for the construction of the tanks and those parts of the machine which come into contact with the material being dyed may be of a stainless nature such as copper, tin, Monel-metal, etc., and constructed heavy enough to withstand the pressure applied.

While the present disclosure shows just a single arm unit, it is possible to build my machine and use my method by the use of multiple arms to take care of large size lots thereby increasing the capacity of the machine and method.

While I have illustrated my invention in different ways and using different construction, materials, means, and methods still I do not intend to limit myself to those particular means, designs, methods, materials, or construction, as it is apparent that other means, designs, construction, methods, and materials may be employed for obtaining the same results within the scope of the claim without departing from the scope or spirit of my invention.

I claim:

A skein dyeing apparatus comprising: a closed vat, said `vat having side walls converging toward the bottom of said vat, said vat also having` end walls, an arcuate cover for said vat mounted on said walls, a rotatable, perforated tube mounted near the top of said vat, said tube having discs at each end, at least a portion of said discs being located within the space defined by said arcuate cover, a rod rotatably mounted on and extending between said discs, a weighted iin mounted on said rod and extending substantially between said discs, a supply tank below said vat, a conduit leading from said vat to said supply tank, said conduit containing a pressure relief valve, means to circulate liquid from said supply tank to said perforated tube, and means to rotate said perforated tube.
